I agree, its no fun having bots fighting bots for leaderboard spots!

But multi accounting is not unsolvable, it requires one or both of restricted API access or KYC. Ideologues will complain that KYC isn't decentralised, which is fine, they can keep playing doomed decentralised games that get leeched dry by thousands of multi accounters. That's the choice on the table for the devs and the community: a) a game with KYC or restricted API with a sustainable economy, and without all these silly restrictions on gameplay, or b) a decentralised pump and dump game that ultimately has all its value sucked out of it, even if there might be a random pump at the next bull market before the inevitable.

It's literally impossible to "remove any remaining advantages bots have" as the OP suggests. Removing value from bots removes value from players too.
